    You may need to repost your question. I know less about how this fixya site works than I'd like. No help menu here. But it seems that once anyone gives an answer to a question, that question is removed from the unanswered quick view list. And I can't figure out how other techs can find it & join the discussion. If you repost I'll not give an answer so some one else can try to help you out.

OK this could be quite a few things. But my bet is air or fuel. Verify & I mean look at it. Is the Air filter clean so many shops are charging for but not replacing them. Last 3 cars I work on had this issue. Next MAP sensor may need cleaning or replacement. This is a known issue on these cars. If these check OK I would have fuel pressure checked next. you may have a clogged fuel filter or a failing pump.

Why does it occasionally lose power going uphill?


Sounds like it's starving. Change your filters lately. How about those O2 sensors especially the upper ones.

2006 malibu ss traction light on and tranny shifting hard reset computer shifts fine


The error could be in transmission abs airbags or engine among others. As many modules these days is staggering. Suggest take it to dealer. Not many mechanic shops have the ability to check codes or repair suspension , airbag or other manufacturer specific design ed systems. And you will get much more knowledgeable mechanic. Could be as simple as wheel bearing loose, most prelevent cause, but without codes from computer making lights come on, were dead in water. Transmission in limp home mode makes me lead to guess, ya just a guess, to say you are missing a speed sensor. Signal. Now car will still start without crank sensor, tourque converter input speed sensor, trans output speed or any of the four abs wheel speed. Like I said loose wheel bearing causes mag pick up wheel speed sensor to miss counts, ad has predetermined amount of pulsed electrical signals it produces, when one not equal to others then pops code. Good luck write what code is found and where. Thx

Chevy 2002 Malibu ERG valve


Symptoms of a bad EGR valve are usually stumbling idle or the engine stalling when the car is warm (normal operating temperature). Find the EGR valve and locate the vacuum line attached to it. Start the engine cold and wait for it to warm up. When the engine starts to stumble, pull off the vacuum line. If the EGR is bad, the engine idle will stabilize and no longer stumble.

1998 chevrolet k1500 4wd. 5.0 liter.truck runs fine untill putting load on it.Pulling trailer uphill on long grade it starts to shake and miss.If you stay in throttle long enough service engine soon light...


Your ignitoin module may not be able to handle the work load anymore. If it gets hot, it will miss. You'll need to replace it. If you do a lot of towing, I suggest a performance unit from ACCEL or MSD

No Power


Check for restricted exhaust. Hook a vacuum/pressure gauge into hose going to DPFE sensor. You should read 1 PSI or less at idle and 3-4 psi at wide open throttle, anything more than this is a restriction which would most likely be a stopped up catalytic convertor.
